UNITED STATES PATENT EEICE.

GEORGE SHELLEY, OF WILKES-BARRE, PENNSYLVANIA.

HYDRANT.

SPECIFICATION forming part of Letters Patent No. 260,904, dated Julyll,1882.

Application led March 3, 1882. (No model.)

To all lwhom fit may concern.-

Be it known that I, GEORGE SnELLEY, a citizen of the United States,residing at Wilkes- Barr, in the county of Luzerne and State ofPennsylvania, have invented certain new and useful Improvements inHydrants; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

This invention relates to improvements in hydrants, and has for itsobject a hydrant that will not freeze, and one that will be efficientand simple in all its operations; and it consists in the constructionand arrangement ot' the several parts, as will behereinafter fullydescribed, and specifically pointed out in the claims.

In the drawings, Figure lis a side view, and Fig. 2 is a verticalsection, of a hydrant constructed according to my invention; and Figs.

3 and 4 are detail views, showing the means I employ for elevating anddepressing the discharge-pipe.

The outer casingof my hydrant is composed of the central cylinder, A,the upper cylinder,

A', the lower cylinder, A2, and the top piece,

A3. The top piece, A3, is secured to the upper cylinder by bolts. Theupper cylinder is secured to the middle cylinder by set-screw a,

passed through threaded opening in cylinder A', and bearing againstupper portion of the cylinder A. 0n the inner rear side of the uppercylinder I provide a lug, a', the under side of which forms a squareshoulder, which rests down on the top of cylinder A, as shown. Themiddle and lower cylinders arev secured together bya threaded joint. Thelower portion of the cylinder A2 is reduced in size, forming the pipea2, which is formed with a male thread to provide connection for thesupply-pipe. The inside ofthe upper portion of the pipe a2 is cut with afemale thread to receive the threaded end of tube b. The tube b isscrewed into the inside of upper portion of pipe a2, and it is extendedupward nearly to the joint of the lower and middle cylinders, as shown.In

the outer sides of the tube b', I providea series of two or moregrooves, b', extended from near the top of the tube. These grooves maybe made an inch or more long, as desired. These grooves are designed toconvey otf the water contained in the discharge-pipe when the supply isshut on", and the manner in which these grooves operate in connectionwith the plunger on lower end of discharge-pipe to carry off the waterwill be hereinafter fully described.

b2 is an opening leading out through the cylinder A2 near its bottom.

The front o f the upper cylinder, A', is formed with the opening c,through which is passed the discharge-nozzle, and this opening iselongated vertically to permit the upward and downward play of thedischarge-nozzle as this nozzle, in connection with thedischarge-pipe,

,is elevated and depressed.

The front portion of the top piece, A3, is cut away to provide passagefor the handle, and so as to permit the motion of the handle from sideto side, as is required in the operation of my device. 'lhe top piecealso is cut with an annular bearing, c', for the top of the circlecarrying the curved cams, as shown.

d is a disk. It is provided on its upper and lower side with semi-roundridges or projections extended across the disk and slightly beyond it oneither side. These ridges are placed one above the other on oppositesides of the disk, and beyond the edges of the disk they form aperfectly-round rod, through which I cut inclined slots d2 d2.

e is the handle. It is connected to the circle e', which is placed and`bears between the annular bearing c' of top piece and the top of uppercylinder, A'. On the inner side of circle e', I provide two threads, e2e2, which are curved with and extend from upper to lower sides of thecircle e. The inner side of these threads c3 is made in the are of acircle of proper size to permit them to pass freely over the edge of thedisk d, and the ends ofthe threads are formed a sufficient distanceapart to permit the passage between'them of; theridges or projections d'on disk d. These threads e2 work in the inclined slots d2 in the ends ofthe ridges or projections d' on disk d, and raise and lower said diskand the dis- IOO . I .I I I i charge-pipe, nozzle, &c which are properlyconnected, as will be described, as the handle e is turned from side toside.

d3 is a rod made fast to disk d, and extended down and formed with itslower end threaded and screwed into top ot' T-jointf. The nozzle f isconnected to side of the said T-joint, and extended through the openingin upper cylinder, and the discharge-pipe]c2 is screwed into lower endof said T-jointf.

g is the plunger, secured by threaded joint to the discharge-pipe f2,and operating within the lower cylinder, A2. This plunger is formed witha shoulder, g', below whichthe outer side oftheplungeristhreaded,formingthe threaded extension which receives theannular washer g2 and jam-nut g5, as will be described.

g2 is a washer made to dt snugly the sides of the cylinder A2, andsecured up against the shoulder g' by jam-nut g5. This washer g2prevents the waste water from getting into the cylinder A, and alsosecures for the plunger a steady action and prevents wear ot' both theplunger and insideot the casin g. This washer may be readily replacedwhen worn.

g3 is an annular cup-washer, secured to under side of plunger and heldby jam-nut g4. This washer fits closely the sides of the tube b, andthere is space let't between the sides of the upper portion of thiswasher and the inner sides of the plunger, so that when the pressure ofthe water is on it the washer hugs closely the sides of the tube andprevents all leakage. Vhen the plunger is forced down in the operationof closing th'e hydrant this cup-washer straddles the grooves b andpermits the water which is left in the discharge-pipe to pass out.

h is a valve cast on inner side of plunger and connected intwo or moreplaces, so as to leave space for the water to pass freely when thehydrant is turned on. To the under side ot' this seat I tix properpacking h. The seat and packing are made of sufficient diameter to coverthe opening ot' tube b when the hydrant is shut down, as will bedescribed.

The operation of my deviceis simple, and will be readily understood onreference to the drawings. When the plunger, Sac., are in the positionshown in Fig. 2,the water passes freely up and out of the nozzle. Thenwhen the handle c is turned and by its connection with the disk d forcesthe discharge-pipe, plunger, 85o., downward, the seat and packing restdown over the opening of tube b and shut oft the supply of water. In theaction of shutting oft' the water by depressing the plunger thecup-washer g3 is pressed down and straddles the grooves b', and thewater contained in the discharge-pipe runs out through the said groovesb into the cylinder A2 and escapes through the opening b2, thusobviating the trouble arising by freezing ofthe water in thedischarge-pipe. Ordinarily' no vwater will get in the cylinder A outsidethe discharge-pipe f2,- but in case any should get in there by reason ofleakage or otherwise it will tlow out through the opening b3, which Iprovide for such purpose.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1si 1. In a hydrant having the cylinder A2 andinletpipe b, the combination, with the plunger g, having the annularshoulder g and threaded extension, of the jam-nut g5, nut g", annularwasher g2, and cup-washer g3, substantially as and for the purposes setforth.

2. The combination, with the plate or disk d, connected with thedischarge-pipe, and provided in its sides with inclined slots d", of'the inclined threads e2, iitted within the circle e', rigidly connectedto the handle e, substantially as set'forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE SHELLEY.
